The only examples of this species I have seen were com- 

 municated by Mr. Thompson, who took them from off a 

 Shieldrake (Tadorna Bellonii), at Belfast, all of which

 a supposition that the specimens in the British Museum, 

 named tadornce, are the same species, especially as they are 

 of the same genus.
